Only if by 'uncompromised' you mean:
- Limited video card options
- No internal drive bays
- No internal PCI Express slots
It's a slick rig, but it only covers one niche of the workstation market. Apple got the design to where it is by opting to eliminate choice from many of the design variables, a compromise. Other workstation vendors choose to compromise in the other direction by having systems that may require more than one fan but also allow for user choice in what powers the system.
I should point out my 4 fan workstation is nice and quiet despite all the potential spinny bits. Like the Apples of old the primary cooling fan is a low RPM large diameter unit that is silent when working. The second fan is in the power supply and thermally controlled. Again, silent under the max stress my payload is able to put it under. The last two fans are sandwiched between a radiator and again are thermally controlled and so far have only spun up into the audible range once while I was running a torture test but were still quieter than my xBox 360 at idle. My system sits at ear level to my right so it's not getting masked by being under a desk, etc. In comparison to the new Apple workstation it's far larger physically as the primary tradeoff for the customizability I have.
